Abstract

Density functional theory calculations have been used to study the adsorption of glycine, alanine, serine, cysteine, aspartic acid and asparagine on the hydroxylated (100) surface of α-quartz. We found measurable energy differences between the two enantiomers of serine, aspartic acid and asparagine in their most stable states on this surface, while negligible differences in adsorption energies for the most stable minima of enantiomers of alanine and cysteine were observed. Our results provide fundamental information on how amino acids can exhibit enantiospecific adsorption on hydroxylated quartz surfaces.

Physical Chemistry Chemical Physics (PCCP) is an international journal co-owned by 19 physical chemistry and physics societies from around the world. This journal publishes original, cutting-edge research in physical chemistry, chemical physics and biophysical chemistry. To be suitable for publication in PCCP, articles must include significant innovation and/or insight into physical chemistry; this is the most important criterion that reviewers and Editors will judge against when evaluating submissions. The journal has a broad scope and welcomes contributions spanning experiment, theory, computation and data science. Topical coverage includes spectroscopy, dynamics, kinetics, statistical mechanics, thermodynamics, electrochemistry, catalysis, surface science, quantum mechanics, quantum computing and machine learning. Interdisciplinary research areas such as polymers and soft matter, materials, nanoscience, energy, surfaces/interfaces, and biophysical chemistry are welcomed if they demonstrate significant innovation and/or insight into physical chemistry. Joined experimental/theoretical studies are particularly appreciated when complementary and based on up-to-date approaches.
